Unfortunately, there's not simple formula to identifying all of the factors of a number and it can be a tedious process when trying to identify the divisors of larger numbers. To find the factor combinations of the number 271,042,805, it is easier to work with a table - it's called factoring from the outside in.
We start by creating a table and writing 1 on the left side and then the number we're trying to find the factors for on the right side in a table. Then, below that, write the numbers as a negative as well.
| 1 | 271,042,805 | |
| -1 | -271,042,805 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 271,042,805.
Example:
1 x 271,042,805 = 271,042,805
and
-1 x -271,042,805 = 271,042,805
Notice both answers equal 271,042,805
With that explanation out of the way, let's continue. Next, we take the number 271,042,805 and divide it by 2:
271,042,805 ÷ 2 = 135,521,402.5
If the quotient is a whole number, then 2 and 135,521,402.5 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 271,042,805 | |
| -1 | -271,042,805 |
Now, we try dividing 271,042,805 by 3:
271,042,805 ÷ 3 = 90,347,601.6667
If the quotient is a whole number, then 3 and 90,347,601.6667 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 271,042,805 | |
| -1 | -271,042,805 |
Let's try dividing by 4:
271,042,805 ÷ 4 = 67,760,701.25
If the quotient is a whole number, then 4 and 67,760,701.25 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 271,042,805 | |
| -1 | 271,042,805 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 67 | 335 | 737 | 3,685 | 73,553 | 367,765 | 809,083 | 4,045,415 | 4,928,051 | 24,640,255 | 54,208,561 | 271,042,805 |
| -1 | -5 | -11 | -55 | -67 | -335 | -737 | -3,685 | -73,553 | -367,765 | -809,083 | -4,045,415 | -4,928,051 | -24,640,255 | -54,208,561 | -271,042,805 |
